Microchip Technology I2C/USB Bridge Board for maXTouch® Devices

Microchip Technology I2C/USB Bridge Board (ATUSB-I2C-AUTO-PCB) is designed to connect maXTouch® Devices to a PC via the USB port. The ATUSB-I2C-AUTO-PCB Board provides an interface to convert I2C and debug signals to USB and communicate with PC-based development applications. The USB-I2C-AUTO-PCB automatically adapts the voltage levels for SDA, SCL, /CHG, /RESET, DBG_CLK, and DBG_DATA signals by using built-in Level Shifters for both Object-Based Protocol (I2C) and DBG buses. The valid VDD levels for these signals are between 1.6V and 3.6V. The communication interface between the Bridge IC and the target can be handled either via the level shifter or by bypassing them.
